What intermolecular forces are present between two molecules of ch3cf3?
The intermolecular forces present in CH3OCH3 are: Dispersion forces and dipole-dipole forces.
What intermolecular forces does polystyrene have?
Polystyrene has a very high molecular weight with its polymer chains interacting through weak, intermolecular forces, or Van Der Waals forces, even though each hydrocarbon chain has high intramolecular strength.
What type of intermolecular force is CH3CH2OH?
Only dispersion forces are present and these are largest in the longer chain alkane as it has more electrons (more bonds). Both molecules possess dipole moments but CH3CH2OH contains hydrogen bonded to an electronegative element so H-bonding is possible.
What intermolecular forces are present in K2SO4?
| Type | Example | Forces |
|---|---|---|
| Ionic | NaCl, K2SO4 | Electrostatic attraction |
| Metallic | Fe, Ag, Cu | Electrostatic attraction |
| Molecular | H2, O2, CH4 | van der Waals forces (dispersion, dipoloe-dipole, H-bond) |
| Network | Graphite, diamond (C), Quartz, etc. (Si) | Covalent-directional electron pair bonds |
What intermolecular forces are present between two molecules of Ch₃ch₂sh?
CH₃CH₂SH is a polar molecule that will have dipole-dipole interactions between two molecules. Dispersion forces will also occur because all molecules have dispersion forces.
What type of intermolecular force is CHF3?
dipole – dipole interaction
The strongest intermolecular forces in each case are: CHF3 : dipole – dipole interaction. OF2 : London dispersion forces. HF : hydrogen bonding.
How do you make polystyrene in a lab?
Polystyrene can be produced in the school laboratory as a demonstration. Set up a water bath using a 250 mL of boiling water. Add 0.1 g of di(dodecanoyl) peroxide to 5 mL of styrene 4 in a boiling tube.
How does styrene become polystyrene?
The Basics: When styrene molecules are linked together into a polymer, polystyrene is created. Polystyrene is an inert plastic that can be used to make many products, such as disposable plates, cups and other foodservice packaging products.
Which has stronger intermolecular forces CH3OCH3 or CH3CH2OH?
CH3OCH3 has stronger intermolecular attractions because it has hydrogen bonding, while CH3CH2OH does not. CH3CH2OH has stronger intermolecular attractions because it has hydrogen bonding, while CH3OCH3 does not. CH3CH2OH has stronger intermolecular forces, and it weighs more.
Is ch3 ch3 dipole dipole?
H2CO is a polar molecule and will have both dipole-dipole forces and London dispersion forces while CH3CH3 is a non-polar molecule and will only have London dispersions forces.
What type of bonds are in K2SO4?
Some compounds can contain both ionic and covalent bonds such as K2SO4… the sulfate ion is held together with covalent bonds… the potassium ions are ionically bonded to the sulfate ions.
